Abstract
Changes in mass and viscoelasticity of chitin layers in fungal cell walls during chitinase attack are vital for understanding bacterial invasion of and human defense against fungi. In this work, regenerated chitin (RChitin) thin films mimicked the fungal chitin layers and facilitated studies of degradation by family 18 chitinases from Trichoderma viride (T. viride) and family 19 chitinases from Streptomyces griseus (S. griseus) that possessed chitin-binding domains (CBDs) that were absent in the family 18 chitinases. Degradation was monitored via a quartz crystal microbalance with dissipation monitoring (QCM-D) in real time at various pH and temperatures. Compared to substrates of colloidal chitin or dissolved chitin derivatives and analogues, the degradation of RChitin films was deeply affected by chitinase adsorption. While the family 18 chitinases had greater solution activity on chitin oligosaccharides, the family 19 chitinases exhibited greater surface activity on RChitin films, illustrating the importance of CBDs for insoluble substrates.

Abstract
Non-enzymatic degradation of wood via a chelator-mediated Fenton (CMF) system is the primary method for initial attack in brown rot fungal decomposition of wood, the most common type of fungal degradation of terrestrial carbon biomass on the planet. In this study, the degradation of thin films of cellulose and chitin by a CMF system was investigated and compared to enzymatic hydrolysis. The kinetics of the rapid cellulose and chitin deconstruction and the morphologies of the degraded cellulose and chitin surfaces were studied by quartz crystal microbalance with dissipation monitoring (QCM-D) and atomic force microscopy (AFM), respectively. The QCM-D results quantitatively indicated that ~90 wt% of the regenerated cellulose or chitin was capable of being deconstructed by CMF action alone. While enzymatic degradation was consistent with stripping of layers from the surface of the cellulose or chitin films, the CMF process exhibited a pronounced two stage process with a rapid initial depolymerization throughout the films. The initial degradation rates for both model surfaces by the CMF system were faster than enzyme action. This research suggests that the CMF process should be applicable for the deconstruction of a wide variety of polysaccharides over Fenton chemistry alone.

Nuclear-targeted p53 and DOX co-delivery of chitosan derivatives for cancer therapy in vitro and in vivo. Colloids Surf B Biointerfaces 2019; 183:110440.

Abstract
The nucleus is one of the most important cellular organelles. Chitosan-grafted poly-(N-3-carbobenzyloxy-lysine) (CCL) decorated with human immunodeficiency virus-1 transactivator of transcription (TAT) can co-deliver p53 and doxorubicin into the nucleus simultaneously, such that their antitumor functions are exerted. However, TAT-CCL has been shown to have an anti-tumor effect only in vitro; the effect in vivo was unsatisfactory. Here, a unique nucleus-targeted delivery system based on amidized TAT (aTAT)-CCL with aTAT functional on the surface was designed to achieve a highly efficient nucleus-targeting gene and drug delivery system for effective cancer cell elimination in vitro and in vivo. In this delivery system, TAT is amidized to inhibit its nonspecific interactions. Confocal laser scanning microscopy observations revealed that if aTAT-CCL was incubated in pH 5.0 acetate buffer solution for 24 h before use (named aTAT-CCL-HB), more aTAT-CCL-HB entered the nucleus compared with aTAT-CCL or CCL. aTAT-CCL-HB can also achieve high gene transfection and drug delivery efficiencies and low viability in HepG2 cells. However, only aTAT-CCL achieved extensive circulation in the blood compartment and high antitumor activity in vivo. Amidization of TAT in vectors may become a promising strategy for nucleus-targeted delivery systems, especially in in vivo applications.

Abstract
Due to the increasing incidence of tumor metastasis and multidrug resistance, even though a combined use of chemotherapy and radiotherapy is introduced, the 5-year average survival rate of an advanced nasopharyngeal carcinoma (NPC) patient still remains low. Hence, targeted slow-release anticancer drugs represent a potential therapy for advanced NPC. In this study, pH and redox dual stimulation-responsive folate-targeted folic acid - β-cyclodextrin - hyperbranched poly(amido amine)s (FA-DS-PAAs) nanocarriers for codelivery of docetaxel (DOC) and tissue factor pathway inhibitor 2 (TFPI-2) for NPC therapy are discussed. Physical and chemical properties, in vitro DOC-release properties, folic acid (FA)-targeting, transfection, Western blotting, DOC and TFPI-2 codelivery, therapeutic properties, targeted inhibition, and biocompatibility, in vivo FA-targeting, toxicity, and therapeutic properties of FA-DS-PAAs/DOC/TFPI2 nanoparticles are evaluated. The results indicate that the 200 nm low-toxicity FA-DS-PAAs/DOC/TFPI2 nanoparticles could enhance TFPI2 gene expression, make cancer cells more sensitive to DOC, induce cell apoptosis, and reduce cell invasion more effectively compared with monochemotherapy. With respect to the targeted release of drugs (DOC and TFPI2) in tumor cells, FA-DS-PAAs/DOC/TFPI2 is associated with the slowest growth rate of tumor and the smallest volume of tumor, so this study demonstrates the best synergetic antitumor effect. We anticipate that this study is important because it not only provides a potential new therapy approach for NPC but also paves the preclinical way for potential application of FA-DS-PAAs/DOC/TFPI2.

Abstract
We developed a high-efficiency nucleus-targeted co-delivery vector that delivers genes and drugs directly into the nucleus of cancer cells. The system is based on grafted poly-(N-3-carbobenzyloxy-lysine) (CPCL) with transactivator of transcription (TAT)- chitosan on the surface. It is designed to perform highly efficient nucleus- targeted gene and drug co-delivery. Confocal laser scanning microscopy (CLSM) revealed that more TAT-CPCL entered the nucleus than does CPCL alone. The TAT-modified vector serves as a gene and drug co-delivery mechanism to achieve high gene transfection efficiency, high apoptosis and low viability in HeLa cells. TAT-CPCL may become a vector for cancer gene treatment and a template for designing better co-deliver systems.

Abstract
Cleavage of ester bonds by extracellular microbial hydrolases is considered a key step during the breakdown of biodegradable polyester materials in natural and engineered systems. Here we present a novel analytical approach for simultaneous detection of changes in the masses and rigidities of polyester thin films during enzymatic hydrolysis using a Quartz Crystal Microbalance with Dissipation monitoring (QCM-D). In experiments with poly(butylene succinate) (PBS) and the lipase of Rhizopus oryzae (RoL), we detected complete hydrolysis of PBS thin films at pH 5 and 40 °C that proceeded through soft and water-rich film intermediates. Increasing the temperature from 20 to 40 °C resulted in a larger increase of the enzymatic hydrolysis rate of PBS than of nonpolymeric dibutyl adipate. This finding was ascribed to elevated accessibility of ester bonds to the catalytic site of RoL due to increasing polyester chain mobility. When the pH of the solution was changed from 5 to 7, initial hydrolysis rates were little affected, while a softer film intermediate that lead to incomplete film hydrolysis was formed. Hydrolysis dynamics of PBS, poly(butylene adipate), poly(lactic acid), and poly(ethylene terephthalate) in assays with RoL showed distinct differences that we attribute to differences in the polyester structure.
